[IPV4]: Remove unsupported DNAT (RTCF_NAT and RTCF_NAT) in IPV4
- The DNAT (Destination NAT) is not implemented in IPV4. - This patch remove the code which checks these flags in net/ipv4/arp.c and net/ipv4/route.c. The RTCF_NAT and RTCF_NAT should stay in the header (linux/in_route.h) because they are used in DECnet. Signed-off-by: Rami Rosen <ramirose@gmail.com> Signed-off-by: David S.
